ASUS ROG Strix Helios II EATX mid-Tower Gaming PC case, with Dual Tempered Glass Side Panels, Support for Graphics Cards up to 450mm Long, Graphics Card Braces and Support for up to 420mm radiators / 90DC00W0-B39000 + FREE DELIVERY !

The ROG Strix Helios II is a premium EATX mid-tower gaming case featuring dual tempered glass side panels, a refined aluminum frame, and a diamond-grille front panel with a 3D-structured front filter. It ships with four 140 x 28 mm performance fans to optimize airflow and thermal performance, and supports motherboard sizes from ITX to EATX as well as serious water-cooling configurations.

Built for showcase systems, the Helios II uses dual 4mm-thick tempered glass side panels set in a brushed-aluminum frame. The aluminum front panel is milled with high-precision CNC technology and anodized, while diagonal slashes and rounded edges give the chassis a streamlined, race-inspired appearance.

The Helios II balances cooling and acoustics with four pre-installed 140 x 28 mm fans that provide strong airflow while keeping noise low at 29 dB(A). The design delivers measurable performance—103 CFM airflow and 2.3 mmH2O static pressure—suitable for demanding builds.

Helios II is engineered for expansion and high-end components, accommodating GeForce RTX™ 5090 graphics cards and complex water-cooling setups. It supports radiators up to 420mm in the front and 360mm at the top, and includes space for installing a pump and reservoir for custom loops.

A rear push button releases one side panel for tool-free access to the interior; the tempered glass is hinged at the bottom so it can swing open and rest at an angle, or be fully removed for easier tinkering and maintenance.

The front I/O includes two USB 20Gbps Type-C ports with support for 60 Watt fast charging where compatible, an ARGB lighting control button for Aura Sync, and PWM-based premium fan speed control to adapt airflow automatically.

Carry your build comfortably using the X-shaped woven fabric straps, which combine style and ergonomics and are tested to support up to 50kg for reliable transport to events like LAN parties.
